USB 3.2 boasts the maximum transfer rate of 20 Gbps which is twice the USB 3.1 Gen 2 so far. It corresponds to "multi-lane operation" that allows data to be transferred simultaneously in multiple lanes, and if the device is compatible, the speed of 16 Gbps or more will come out even with the conventional USB 3.0 compatible cable.

New specification of USB "USB 3.2" is multi-lane operation if it is compatible terminal, the maximum speed is doubled USB 3.1 - GIGAZINE



According to the USB-IF, a chip supporting 20 Gbps USB 3.2 will be released in 2019. Although UUSB-IF does not mention the name of a company developing a chip, it is said that motherboard for high-end PC compatible with USB 3.2 will be announced in the summer of 2019, and compatible peripheral devices are compatible Because of the problem, it is thought that it will be popularized in about 2020 in general.

USB 3.0 with a maximum transfer rate of 5 Gbps announced in 2008 enables "High Speed" USB 2.0 with maximum transfer speed of 480 Mbps or "Full Speed" with overwhelming high-speed communication than USB 1.1 with maximum transfer rate of 12 Mbps It was named "SuperSpeed USB".

In USB 3.1 announced in 2013, it was said that the maximum transfer rate will be 10 Gbps, which is double the USB 3.0. However, USB 3.0 and USB 3.1 were compatible with software layer and device protocols, so USB 3.0 of 5 Gbps communication became the standard name "USB 3.1 Gen 1". And the USB 3.1 of the new 10 Gbps communication became the standard name "USB 3.1 Gen 2" and was named "SuperSpeed USB 10 Gbps"

ArsTechnica insists that the appearance of this USB 3.1 has brought a very confusing situation for consumers. ArsTechnica points out that some vendors also sell 5 Gbps USB 3.1 Gen 1 devices with the phrase "USB 3.1 is supported" for example. Although this selling phrase is certainly not a lie, if it is a customer who does not know the circumstances, even though the maximum transfer speed is doubled, the possibility of being confused with USB 3.1 Gen 2 is also considered sufficiently I will. Also, ArsTechnica criticizes that having both names "SuperSpeed USB" is spurring the confusion.

It is announced that USB 3.2 that will appear in 2019 will be "USB 3.2 Gen 2 x 2" as the standard name and "SuperSpeed USB 20 Gbps" as the name in the market. Although it is not clear when the device equipped with USB 3.2 will appear specifically, it is likely to need more attention than ever so that it will not be confused with a similar name when it is on the market. is.
